Examination of Water Electrolysis and Oxygen Reduction As Self-Discharge Mechanisms for Carbon-Based, Aqueous Electrolyte Electrochemical Capacitors
Bibliographic record
Abstract
Water electrolysis and oxygen reduction as possible self-discharge mechanisms for carbon-based, aqueous H 2 SO 4 electrolyte electrochemical capacitors is examined through a comparison of the predicted and actual effects of varying the dissolved oxygen and hydrogen content on self-discharge. Water electrolysis, in the form of oxygen evolution, is not the self-discharge mechanism on the positive electrode, although, the self-discharge profile is consistent with an activation-controlled Faradaic discharge or charge redistribution mechanism. The addition of hydrogen evidences no change in self-discharge from the negative electrode, and the profile is consistent with a diffusion-controlled mechanism, suggesting water electrolysis through hydrogen evolution is not the self-discharge mechanism. Oxygen reduction causes a large increase in self-discharge on the negative electrode which necessitates purging the cell of oxygen. As such, water electrolysis is likely not the cause of self-discharge in carbon-based, aqueous electrolyte electrochemical capacitors but oxygen reduction is a cause of increased self-discharge on the negative electrode.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
